Sodium sulfide, also known as smelly alkali, smelly soda, alkali sulfide, is an inorganic compound, the chemical formula Na2S. Soluble in water, insoluble in ether, slightly soluble in ethanol. It burns when touched on skin and hair, so sodium sulfide is commonly known as alkali sulfide. When exposed to air, sodium sulfide emits toxic hydrogen sulfide gas that smells like rotten eggs.
Sodium sulfide (alias: alkali sulfide), is a common inorganic chemical raw material. Industrial sodium sulfide because of impurities its color is red and yellow, so it is usually called red sodium sulfide, sodium yellow sulfide.

Applications 1, the dye industry for the production of vulcanized dye, is the raw material of vulcanized blue and blue. Used in the printing and dyeing industry as an aid to dissolving sulphide dyes. In the leather industry, it is used for hydrolysis to remove hair from raw skin, and it is also used to prepare sodium polysulfide to accelerate the immersion of dry skin and help softener. Used in the paper industry as a cooking agent for paper. In the textile industry, it is used for denitrification and nitration reduction of artificial fiber, and mordant for dyeing cotton fabric. The pharmaceutical industry uses phenacetin and other antipyretic drugs. In addition, it is also used to make sodium thiosulfate, sodium hydrosulfide, sodium polysulfide and so on. 2, adding appropriate amount of sodium sulfide in aluminum and alloy alkaline etching solution can significantly improve the quality of the etching surface, but also can be used for the removal of zinc and other alkali-soluble heavy metal impurities in alkaline etching solution. 3, sodium sulfide can also be used in direct plating conductive layer processing, through the reaction of sodium sulfide and palladium to form colloidal palladium sulfide to achieve the purpose of forming a good conductive layer on non-metallic surface. 4, used as corrosion inhibitor. It is also the raw material of sodium thiosulfate, sodium polysulfide, sulfide dyes and so on. 5, used in the manufacture of sulphide dye, leather hair removal agent, metal smelting, photography, rayon denitration.
